condenser and air handler same brands and same capacities as old units. ducts replaced with new R6 but all same size.
72 degree return air into airhandler and 55 degree air from air handler four feet out into supply plenum.

I agree with duct dr, insulate the drains for the first couple of feet. The attic is hot and humid, the water that is condensation off the coils is in the 50* range. So you have that cold water flowing out the drain and some staying in the trap. It is normal, but you can insulate it to cure it.
